Recently purchase a new 64GB itouch,thinking would be breeze to install music, and synch with my computers.
So far have had to reinstall OS6, spent about 6 hours talking to the mac support people trying to de authorise computers, told have to wait 6 months to rectify problem XX!!!@@### because I authorized computers.
What is the matter with the people, I have about 6+ devises and want to access my music.
Mac rules are out of keeping with peoples use of computers, and lifestyle loss of computers. Then after all this told I could send an email to explain the failing of their system so help apple rectify their problem.
I want a refund.
This product is more problem than it worth.
2/10 for user friendliness.

You can authorize up to 5 computers for use with a single iTunes account. You can de-authorize each computer individually from within iTunes, or de-authorize them all once a year from your iTunes account. I'm not aware of any limit as to how many devices you can register with a given iTunes account.

Maybe you should try and explain the problem in more detail, because what you are describing shouldn't be as difficult as you are making it out to be.

The 5 computer limit only applies to PCs or Macs. Not iOS devices. You can sync unlimited devices to an iTunes library.
